Comparative analysis of atmospheric radiative transfer models using the Atmospheric Look-up table Generator (ALG) toolbox (version 2.0)
2019
Abstract. Atmospheric radiative transfer models (RTMs) are software tools that help researchers in understanding the radiative processes occurring in the Earth's atmosphere. Given their importance in remote sensing applications, the intercomparison of atmospheric RTMs is therefore one of the main tasks used to evaluate model performance and identify the characteristics that differ between models. This can be a tedious tasks that requires good knowledge of the model inputs/outputs and the generation of large databases of consistent simulations. With the evolution of these software tools, their increase in complexity bears implications for their use in practical applications and model interco…
How alternative food networks work in a metropolitan area? An analysis of Solidarity Purchase Groups in Northern Italy
2019
AbstractOur paper focuses on Solidarity Purchase Group (SPG) participants located in a highly urbanized area, with the aim to investigate the main motivations underlining their participation in a SPG and provide a characterization of them. To this end, we carried out a survey of 795 participants involved in 125 SPGs in the metropolitan area of Milan (Italy). Taking advantage of a questionnaire with 39 questions, we run a factor analysis and a two-step cluster analysis to identify different profiles of SPG participants. Our results show that the system of values animating metropolitan SPG practitioners does not fully conform to that traditionally attributed to an alternative food network (AF…
‘Experimental Union’ and Baltic Sea cooperation: the case of the European Union’s Strategy for the Baltic Sea Region (EUSBSR)
2018
In the past, Baltic Sea cooperation has been characterized by a plethora of actors, embracing a wide range of policy objectives, such as the establishment of a good environmental status for the regional sea. In 2009, the European Council endorsed the European Union’s (EU) Strategy for the Baltic Sea Region (EUSBSR) as a new tool in the repertoire of Cohesion Policy and European Territorial Cooperation (ETC). The EUSBSR seeks to foster cross-sectoral coordination and functional cooperation in policy areas of ‘macro-region-level’ relevance, such as transport infrastructure, economic development and environmental protection – thus projecting a ‘soft space’ of transnational Baltic Sea cooperati…
Commoning of territorial heritage and tools of participated sustainability for the production and enhancement of agro-environmental public goods
2021
AbstractThe purpose of this paper is to analyze how the commoning heritage processes find application for the production of agro-environmental public goods in contexts of high socio-economic marginality and environmental vulnerability, characterized by abandonment and from the consumption of agricultural land for food use. The purpose is to understand how these processes are able to influence, at local level, the governance processes for the implementation of environmental protection strategies. The survey made it possible to verify how the commoning processes aimed at the production of agro-environmental goods generate territorial resilience, understood as a community competence able to st…
Resonancia cultural y consonancia informativa como elementos favorecedores de la simbiosis discursiva entre activismo y periodismo en protestas educa…
2020
El movimiento neocon que impulsó la protesta contra Educación para la Ciudadanía se reactivó con el anuncio del Ejecutivo de Pedro Sánchez de introducir una nueva asignatura de valores cívicos y éticos en el currículo escolar. Esta investigación analiza los mensajes difundidos por las principales organizaciones conservadoras para determinar el protagonismo que este tema tuvo en su producción comunicativa y si responden a un marco de acción colectiva. Además, se contrasta dicho discurso con el que plantearon las mismas entidades entre 2004-2008 y se estudia su reproducción en la prensa ideológicamente afín. Se analizan los mensajes de estos grupos en Twitter (n = 131) y en sus webs (n = 11) …
Alain Badiou y la educación como proceso de subjetivación a través de verdades
2021
El siguiente texto presenta algunas tesis acerca de lo que puede aportar la obra del filósofo francés Alain Badiou en el debate acerca de la situación actual de la educación. Para ello se hará una lectura de su obra en clave propedéutica. La hipótesis de partida es que dicha obra puede leerse como un proyecto de recuperación de la filosofía entendida como una educación a través de verdades. Para ubicar esta tesis en el debate educativo contemporáneo se utilizará la teoría elaborada por Gert Biesta, quien ha construido en las últimas décadas un sistema de pensamiento que ofrece un marco teórico con el que fundamenta propuestas educativas alternativas a las tendencias individualistas, funcion…

Strength and ductility of RC jacketed columns: A simplified analytical method
2016
Abstract Reinforced concrete (RC) jacketing is a common method for retrofitting existing columns with poor structural performance. It can be applied in two different ways: if the continuity of the jacket is ensured, the axial load of the column can be transferred to the jacket, which will be directly loaded; conversely, if no continuity is provided, the jacket will induce only confinement action. In both cases the strength and ductility evaluation is rather complex, due to the different physical phenomena included, such as confinement, core–jacket composite action, preload and buckling of longitudinal bars. Although different theoretical studies have been carried out to calculate the confin…
Review of push-out and shear response of hybrid steel-trussed concrete beams
2018
The hybrid steel trussed concrete beams examined in the present study are comprised of two principal components, i.e., a steel joist with inclined rebars, realized in industry, which is welded to a smooth steel plate and then embedded within the concrete cast in situ. The paper presents first the state of the art on laboratory tests and analytical modeling of the steel-to-concrete stress transfer mechanism investigated by push-out tests. Next, the most relevant scientific contributions currently available in the technical literature regarding experimental investigation on actual shear behavior are summarized and discussed. Lastly codes and analytical models are reviewed.
Fatigue methodology for life predictions for the wheel-rail contact area in large offshore turret bearings
2016
The present report presents a fatigue life prediction method for large roller bearings applied in the turret turn table for large loading buoy units. The contact points between wheel and rail in these bearings are subjected to a multi-axial fluctuating stress situation and both surface wear and fatigue cracking may occur. A methodology based on the Dang Van fatigue criterion is adopted. The criterion is based on an equivalent stress defined as a combination of the fluctuation of the shear stress from its mean value at a critical plane and the associated hydrostatic stress at the given time. The present work is supporting the theoretical model by extensive laboratory testing. Both full scale…
